Question about 1999 Pontiac Grand Am GT

1 Answer

My 99 grand am is idling fast and slipping?

My 99 grand am is idling fast and jerking when being pulled into gear....''slipping'' maybe? It takes the car a bit to change gears... what could the problem be?
Before it started doing this I replaced the lower intake gaskets...could this be a factor?
Code scanner at home has manifold absolute pressure/barometric pressure circuit low input?

I think you have an air leak with this new gasket you fitted that would make the engine run faster as its running very week and drwing secondery air , witch is why you have low presher,, the thumping you get when you put the car in gear is becouse its ticking over too fast it could brake a drive shaft if you dont sort the manyfold gasket out soon, check all the bolts around the intake are tight first, but my gess is its leaking badly

My 2004 mazda mpv jerks to the left then straightens back out. This usually happens when I have to accelerate really fast or right about the time it shifts into the last gear.


Mike, this may be because the left wheel is the dominate drive axle (left axle locks up and pulls hard, while right side slips) when under power. Vehicles that do not have possie drive differentials have this pulling characteristic.

Why does my jeep turn off if I don't toggle the overdrive switch enough?


it stalls with foot in the throttle...... really.? try to say what you and car are doing at the od switch flips.. sure moving fast.
but doing what, up hill down, flat, acceleration, decel, or coasting?

ok, this can be real easy.
engine tuned up is 99%
ever heard of scan tool.
connect it, and log data (or person 2 watches) and log DTC and streaming data?
if the Magic relay called ASD drops the the engine stalls (this is its purpose) and if it did the SCAN TOOL tells you why it did.
every time...
asd class 101.:
http://www.fixkick.com/Jeeps/ASD.html

is transmission stuck in 3rd gear, limphome.??
the trans mission will not stall a car. 99%
that is because the clutch has a stall speed.
and slips greatly at idle, say 800rpm is hot idle , so if say the trans solid locked into top gear. and you came NEAR a stop sign, coasting... and braking.. say.....
and as rpm dropped, the clutch will slip and no trans ever stalls the engine.99% unless the engine is super weak and misfiring hard.
or ASD DROPs !
that is why we scan to see ALL ERRORS> engine and trans.
see?

I have a jerk if I pull away in a low gear or if I stop nd go my bakkie jerks I did check the plugs nd plug wires no fault there what can it be ?


Not sure whether you're running an automatic or manual trans, but, If you're jerking or maybe pulsing when you touch your brake pedal it could be you have warped rotors. If it's an automatic then your trans could be slipping, if it's a manual trans then your clutch could be slipping or your throw-out bearing may not be letting the clutch plate disengage all the way.

1996 Jeep Grand Cherokee 4.0 auto idles good but will only move with it wide open or just barely any throttle


4.0L
what transmission, mines a 5 speed stick so?????
idles good, well that dont take much.
will only move, car moves?
with what wide open ,the throttle?
well just barely throttle is normal, why say that?

my guess is car has low power, or can not go fast in all gears.
is that it?
if yes, that is transmission slip or a weak engine,
transmission slip is easy RPM goes way high car dont move
weak engine acts like brakes stuck on , low RPM deep right foot.
post all symptoms and win, big time.

What is wrong with my car when it jerks in drive


jerks when?

moving the shift lever. with hand?

moving car. in gear,name the gear, drive, L or reverse?

jerks from, 1 to 2nd gear, 2nd to 3? or ? (or when IT down shifts)

pretend we are blind (we are) and cant drive car,(hopeless) and

tell us exactly what works and dont work driving.

hot /cold engine, fast /slow/ accelerating/ decelerating, up hills and what gears.



if engine is hot, is your idle at 800 RPM parked, in park.

y/s

if not the idle controls are out of control and when you shift to drive

IT will jerk. this is an engine problem.

there are lots of other symptoms.

My SUV is choking and it hesitates


which engine? 2L I4 or 2.5L V6?
chocking, it bogs full time.
total loss of power at all times? any speed, any hill, any gear.
is this a A/T or M/T car, the A/T can slip. easy
does the engine lack power, or does the tranny slip.
slipping is easy to discover, the RPM of the engine rise fast
but you go now where fast.
bogging can happen in many modes. (all or just 1: pick one)
all permutations
1: hot engine?
2: cold or both.?
3: wont race even in neutral, but idles ok. at 800 rpm.?
4: only with a fast right foot,called tip in throttle. but recovers.!
5: lost power at all driving loads, and worse on hills.?
6: all the above.?
in a real shop, i drive it and in a few minutes all the above is seen and vastly more, that is why online help is so bad, (me too)
no inputs. = wild guessing.....
heck i even notice things like?
dash volt meter dropping. below 14v at any time running.
overheating
CEL glowing or worse flashing (USA feature , OP never said)
old noises and vibration.
clutch slipping or A/T slipping.
Scan tool connected, and seeing pending codes, or any odd PID behaviors.
bad idle speed, idle speeds not controlled correctly.
and 100 more things, Ill stop here, it's a complex machine.

Why car not going fast in local


Is it an auto? If so maybe your auto trans fluid is low.

If not maybe the clutch has begun to slip. To test that, start the engine, let it idle, put it in 3rd gear, and let the clutch out slowly. The engine should stall, with no slippage or delay in that.

My honda accord 94 jerks when i take off slow


there are many possible problems here. one of them is the throttle position sensor. it is nothing more than a volume switch on a cheap radio. it moves voltage from 0 to 5 v and tells the computer what you want the engine to do. When they fail usually one part of the range quits working which would produce the effect you described As i said this is just one of the possible problems but one you should rule out. Checking it is done by locating the sensor and checking output with a volt meter. maybe go to local autoparts store and read why check engine light is on It should tell you which sensor is bad if that is the problem

2001 Dodge grand caravan sport. Transmission slipping/ jerking. Seems to run only in second gear... still slips and jerks. Smells of burnt trans fluid and the level is low on the dipstick.


I need a little mor info. But the reason for the being stuck in 2nd gear is because when something goes wrong with the tranny. it goes into "LIMP" mode wich keeps the trans. from shifting out of 2nd when you are going forward. It does sound like your trans. is gone out though.
